Obviously, the icing condition is extremely hazardous.Additionally, the pilot lights and burners of gas or oil fired furnaces,water heaters, etc., are sometimes extinguished due to high winds, orerratic winds, which create either a vacuum or down draft to extinguishthe same.

Therefore, it is a principal object of this invention to provide a winddeflector for chimneys and the like.

A further object of this invention is to provide a wind deflector forchimneys and the like which prevents the pilot lights and burnersassociated therewith from being extinguished.

A further object of this invention is to provide a wind deflector forchimneys and the like which events dangerous icing of the vent pipes andhoods due to condensation in subzero temperatures.

A further object of this invention is to provide a wind deflector forchimneys and the like which eliminates the necessity of extending ventpipes to a higher elevation to correct problems created by wind or whenthe surrounding terrain creates a problem.

A further object of this invention is to provide a wind deflector forchimneys and the like which is easily mounted in a variety ofenvironments.

A further object of this invention is to provide a wind deflector forchimneys and the like which is designed to enclose an existingventilating pipe or hood.

A further object of this invention is to provide a wind deflector forchimneys and the like which may be manufactured in various sizes to fitstacks and hoods of different dimensions and which also may beconstructed to fit the pitch of any roof without changing the principalor deflection design of the device.

A further object of this invention is to provide a wind deflector forchimneys and the like which may be installed in a vertical position forthrough the roof ventilation or may be installed in a horizontalposition for through the wall" or side ventilation.

A further object of this invention is to provide a wind deflector forchimneys and the like which is economical of manufacture, durable in useand refined in appearance.

These and other objects will be apparent to those skilled in the art.

This invention consists in the construction, arrangements, andcombination of the various parts of the device, whereby the objectscontemplated are attained as hereinafter more fully set forth,specifically pointed out in the claims, and illustrated in theaccompanying drawings in which:

FIG. 1 is a partial perspective view of the device.

FIG. 2 is a sectional view as seen along lines 2-2 illustrating thedevice extending around the chimney or the like.

FIG. 3 is a top view of the device as seen along lines 33 of FIG. 2;

FIG. 4 is an enlarged sectional view as seen along lines 4-4 of FIG. 3;and

FIG. 5 is a perspective view of one of the deflectors which extendbetween the first and second wire elements.

The deflector of this invention is generally designated by the referencenumeral and is adapted to be positioned around a chimney or the likewhich is generally referred to by the reference numeral 12 in FIG. 2.FIG. 2 illustrates that the chimney I2 is of the through the roof"design but it should be understood that the deflector may be installedin a horizontal position for through the wall or side ventilation. Thedevice may also be constructed to fit the pitch of any roof withoutchanging the principal or deflection design of the device. Further, thesize of the device may be varied to fit chimneys, stacks and hoods ofdifferent dimensions. Preferably, the deflector 10 has a diameter of twofeet and is fifteen inches high.

Deflector 10 generally comprises an open-mesh cylindrical wire element14 having an open-mesh cylindrical wire element 16 concentricallypositioned in a spaced condition within the wire element '14.Preferably, element 14 is constructed of I4 gauge welded wire having 1inch X 1 H2 inch mesh openings. As previously stated, the diameter ofelement 14 is preferably 2 feet. Element 16 is preferably 14 inches indiameter and is constructed of a material identical to that of element14.

A plurality of perforated arcuate baffle elements or deflectors 18 aresymmetrically spaced in the space between the elements l4 and 16 andhave their opposite ends secured thereto by any convenient means such asby wire or the like. The deflectors 18 are preferably constructed ofgalvanized sheet metal having three-sixteenth inch staggered holesprovided therein. Preferably, each of the deflectors 18 are 8 incheswide and 15 inches long. Each of the deflectors I8 has a slight degreeof curvature as illustrated in the drawings. The deflectors are arrangedso as to point outward in a clockwise direction as illustrated in FIG.3.

The numeral20 refers to a welded wire cover positioned at the upper endof the device and which is fastened securely to the elements 16 and 18by any convenient means such as wire or the like. The deflector 10 ispositioned around the chimney or hood 12 as illustrated in FIG. 2 and issecured thereto by a plurality of wires 22. Each of the wires 22 has aprebent hook portion 24 at its inner end which is placed under the rimof the saddle portion 26 of the chimney 12. Each of the wires 22 extendupwardly from the saddle portion 26 at a 45 angle through the element16, deflector 18 and element 14. The outer end of the wire 22 is bentdownwardly so as to secure the same to the element 14. The wires 22securely maintain the deflector 10 in position.

The deflector 10 is a device designed to enclose any existingventilating pipe or hood such as found on gas or oil fired furnaces,water heaters, clothes dryers, plumbing vent stacks,

etc. The deflector may be installed in a vertical position,

horizontal position or on any pitched roof without departing from thedeflection design of the device. In actual field trials and experiments,it has been found that the deflector prevents the extinguishing of thepilot lights and burners due to high winds or erratic winds, which wouldordinarily create either a vacuum or downdraft in the chimney. Thedeflector prevents dangerous icing of the vent pipes and hoods due tocondensation which would ordinarily be formed in subzero temperatures.The deflector eliminates the necessity of extending vent pipes to ahigher elevation which is a practice used by some furnace repainnen incorrecting problems created by wind, or when the surrounding terraincreates a problem. The element 14, deflectors l8 and element 16 deflectthe wind around the chimney or the like so as to achieve the resultsdiscussedhereinbefore. The cover 20 serves to prevent leaves or the likefrom accumulating in the interior of the device.

Thus it can be seen that the deflector accomplishes at least all of itsstated objectives.
